Black backgrounds and such

So I’ve been reading audio reviews for 25 years but sometimes the descriptions etc used still don’t make sense or I question what they are really trying to say. What is a black background for example?  Is it the silence that exists when my system is off ?  Curious if there is some glossary or explanation or even better an audio recording which would provide examples of one descriptor vs another.  It’s kind of like wine but at least when someone says has notes of blackberry I have a reference point!

Thanks for all the responses. So does a small amount of barely audible hiss count against the black background?

im still in search for some glossary that will normalize terms used in reviews. It all reads very poetically but hard to gauge whether certain things are meaningful.

So this is all very interesting information. The one that caught my eye was from lowrider around hiss. Open to ideas how to, within financial reason, reduce that with the below in mind.
- I have 3 dedicated 20amp circuits which are connected to a box about 20 feet away. Box itself is a 200 amp box and I have a second one next two it. 
- lexicon RX-7 amps each have own circuit, a shunyata defender plugged into the empty, and are using shunyata viper zitron power cables
-marantz 8802a and Oppo bro-105d plugged into Panamax pm-5300. Marantz plugged into Panamax with shunyata viper zitron power cable. Panamax plugged into third 20 amp circuit. 
- balanced interconnects used throughout, audioquest Mackenzie 
-speaker cable is audioquest slip 14/4 with 15 foot runs going through the corner wall for about 6 amp inches. Revel studio 2s are biamped and crossed over at 110hz.
